SSL Protocol (Secure Sockets Layer) Released
Netscape releases SSL 2.0, creating the encryption standard that made secure e-commerce and online finance possible.
On February 9, 1995, Netscape Communications released the Secure Sockets Layer (SSL) 2.0 protocol. Before SSL, data sent over the web (including credit card numbers and passwords) was transmitted in plain text, making it easily interceptable by anyone on the network. SSL introduced a layer of encryption between the web browser and the server, visualized by the now-famous 'padlock' icon. It used public-key cryptography (RSA) to establish a secure connection, ensuring privacy and data integrity.
SSL was the catalyst that made e-commerce possible. By creating a trusted environment for financial transactions, it paved the way for Amazon, eBay, and online banking. For the cryptocurrency industry, SSL (now TLS) remains critical infrastructure; while Bitcoin transactions themselves are secured by the blockchain, the entire ecosystem of exchanges, wallets, and APIs relies on SSL to protect user data from hackers. Furthermore, SSL normalized the use of cryptography for the general public, proving that complex mathematical security could be abstracted away behind a simple user interface.
The protocol also established the 'Certificate Authority' (CA) model of trust, where centralized entities verify the identity of websites. This stands in contrast to Bitcoin's 'Web of Trust' or trustless models, offering a valuable comparison in security architectures. SSL's widespread adoption established the precedent that the internet could be a safe venue for financial activity, providing the security layer that would later support the massive ecosystem of Bitcoin exchanges and services.
